How i cant create the "do " button , in order to do the HumanTask?

Hi , how i can create a link or a button , and when user press this link or button , the link redirect to task form.

I’m using API REST , with PHP,

Regards.

Please use a “link” widget and bind it to a URL assembled as following:
http://documentation.bonitasoft.com/accessing-bonita-bpm-portal-and-forms-url-0

Hi Philepe,
I reviewed the bonita documentation previously , and implemented a link , but when i click it , it redirected me to a page with a message like this :

the page doesn’t exist and so on. Only i want to access a form that are there in HumanTask.
http://localhost:8080/bonita/portal/resource/taskInstance/nombre_proceso/1.0/nombre_tarea/content/?id=activity_instance_id

i retrieve the activity instance id , from a table into database , ¿can i have a mistake by this?, ¿Are there any way , in order to retrieve the ActivityInstanceId?
I’m using Bonita 6.5 version ,and PHP not AngularJs, because i had problems with “CORS”.

Thanks
